IANA Registries for BGP Extended Communities
Abstract
This document reorganizes the IANA registries for the type values and
sub-type values of the BGP Extended Communities attribute and the BGP
IPv6-Address-Specific Extended Communities attribute. This is done
in order to remove interdependencies among the registries, thus
making it easier for IANA to determine which codepoints are available
for assignment in which registries. This document also clarifies the
information that must be provided to IANA when requesting an
allocation from one or more of these registries. These changes are
compatible with the existing allocations and thus do not affect
protocol implementations. The changes will, however, impact the
"IANA Considerations" sections of future protocol specifications.
This document updates RFC 4360 and RFC 5701.
